a d1 as std has only mechanical lock on the center diff, if you want air or any locker in the axle you but an after market one or two
Thank you but how does the air locker make the difference? I'm not looking at putting it on my D1 just curious

since you have diffs on a std disco, if you were on soft slippy ground you could lose all forward motion just by 1 wheel slipping, the center diff lock thats engaged by a lever means that to lose forward motion when its engaged you would have to have 2 spinning wheels 1 on each axle, if you put a locker in both axles all 4 wheels would have to spin, because axle lockers are in the axle diff you couldnt easily use a mechanical means of operation so air is often used instead,

Your centre diff lock locks the front and rear prop shafts together but you still have an open diff at each axle.
Extra locks whether air or not would be fitted to the axle diffs locking the halfshaft to each wheel

As @jamesmartin has already said, the D1 is fitted with "difflock" otherwise known as a CDL, that is the differential gear inside the transfer box can be locked so that the front and rear prop shafts are forced to rotate at the same speed; under the "unlocked" condition the speeds that the two shafts will rotate is dependant on the conditions and whether either axle is experiencing wheel spinning.
An "air locker" does a similar thing on whichever axle it's fitted. It locks both wheels on the axle so that they turn at exactly the same speed. It's called an air locker because most are operated by compressed air, unlike the centre diff lock in the T-box which is operated by a mechanical linkage. Such lockable differentials in the axles are aftermarket devices.
